ENGINE WITH A FIXED WING ARTICULATED AT THE TOP OF A MAST.

Abstract

Engin à voile comportant une voilure faite d'une aile mobile, symétrique, dont les 2 demi-ailes ne sont pas dans le même plan, reliée au sommet du mât par une articulation. La voilure est constituée d'une toile tendue sur une armature articulée qui peut se plier ou se déplier à la manière d'un parasol de façon à amener toute la toile dans un petit volume rassemblé autour d'un manche (1) qui sert à la manoeuvre de la voile, ou au contraire à étendre la toile proche d'un plan perpendiculaire au manche (1). L'armature, constituée principalement de 3 barres (2, 3 et 4) est maintenue ouverte par un système de tringlerie à 3 petites barres (8, 9 et 10) dont une extrémité coulisse le long du manche (1). Le tissu (12) proche du bord d'attaque de la voilure peut être cambré à l'aide d'une latte qui se courbe à l'ouverture. APPLICATIONS: Engin de plage, bateaux de sport et de loisir, delta-plane

Description

WING CRAFT WITH AN ARTICULATED FIXED WING AT THE TOP OF A MAST The main patent (registration no. 88 11785) relates to a sailing craft which comprises a sail made of a movable wing, symmetrical along a plane, fixed to the top of a mast by a point located below it in its plane of symmetry using an articulation, this sail comprising a maneuvering bar approximately perpendicular to the lift plane, the wing being made of 2 half-wings making an angle of approximately 40 between them. The pre- sente addition describes a variant of this sailing machine equipped with a folding sail which allows the creation of a sailboat, a windsurf board, a wheeled machine or a hang glider. This sail is made of a canvas or similar (film, envelope, etc.) ten- due to an articulated frame which can fold or unfold like a parasol so as to bring all the canvas into a small, gathered volume around a handle or on the contrary to extend it close to a perpendicular plane- cular to this handle. The sail frame, shown schematically in Figures 1, 2 and 3, is composed mainly of a bar (1), or handle, used for maneuvering- of the sail, and at least 3 bars (2, 3 and 4) which are articulated at one of their ends connected to the top of the handle (1) so as to be able to be either pressed against this handle, or spread apart until they are substantially perpendicular to it. dicular. Figure 4 shows the folded frame. A canvas, or similar, is stretched between the bars (2, 3 and 4), constituting thus the 2 main planes (5 and 6) of the sail. A rope (7), cable, ribbon or similar or other canvas is placed between the bars (2 and 4) so ​​as to be well stretched when the frame is open, and thus constitutes a flexible link which can act as a leading edge for the sail. The frame is held open by 3 small bars (8, 9 and 10) each of which- is connected, at one of its ends, to one of the bars (2, 3 or 4) by a articulation, and at the other end to a part (11) common to the 3 small bars- res (8, 9 and 10), this part (11) sliding along the handle (1) when the sail is folded or unfolded. It is the blocking of this part (11) in one of its extreme positions by means of an appropriate system which blocks the frame in open position, use position. According to a variant, to improve efficiency, the space located between the 2 bar- res (2 and 4), close to the leading edge of the sail, comprises a canvas (12) or similar connecting these 2 bars (2 and 4), this canvas being able to be equipped with a or several flexible slats (13) long enough to bend as soon as the car- lure is open in the use position, because these slats (13) are wedge- between the fixed point at the top of the frame and the flexible link (7), rope or other, stretched which constitutes the leading edge of the sail. According to an improved variant, the sail comprises another triangular piece (14) of fabric, canvas or the like, stretched (open sail) between, on the one hand, the flexible link (7) which constitutes the leading edge of the sail and, on the other hand, the 2 parts of canvas (5 and 6) which constitute the 2 main planes of the sail, this piece of canvas (14) being able to cover the 3 small bars (8, 9 and ). According to a variant, the base of the mast (15) is not fixed to a boat hull but comprises, as shown in figure 5, a small seat (16) on which one sits to use this sail in hang-gliding. The craft is then guided by the orientation given to the bar (1) in relation to the mast (15).

Claims

CLAIMS 1. Sailing craft according to any one of the claims of the main patent- pole characterized in that the canopy is made of a canvas or the like (film, envelope, etc.) stretched over an articulated frame which can fold or unfold like a parasol so as to bring the entire canvas into a small volume gathered around a handle (1) or on the contrary to extend it close to a plane perpendicular to this handle (1).

2. Sailing machine according to the preceding claim 1 characterized in that the frame of the sail is composed mainly of a bar (1), or man- che, used for maneuvering the sail, and at least 3 bars (2, 3 and 4) which are articulated at one of their ends connected to the top of the handle (1) so as to be able to be either tightened against this handle, or separated until they are substantially perpendicular to it, a canvas, or similar, being stretched between the bars (2, 3 and 4), thus constituting the 2 main planes (5 and 6) of the sail, a rope (7), cable, ribbon or the like or other canvas being pla- 3. Sailing machine according to the preceding claim 2 characterized in that the frame is kept open by 3 small bars (8, 9 and 10) each of which is connected, at one of its ends, to one of the bars (2, 3 or 4) by an arti- culation, and at the other end to a part (11) common to the 3 small bars (8, 9 and 10), this part (11) sliding along the handle (1) when folding or unfolds the sail.

4. Sailing machine according to the preceding claim 3 characterized in that the space located between the 2 bars (2 and 4), close to the leading edge of the car- lure, comprises a canvas (12) or similar connecting these 2 bars (2 and 4), this roof- which can be equipped with one or more flexible slats (13) long enough to bend as soon as the sail is open in the position of use, these slats (13) being wedged between the fixed point at the top of the frame and the flexible link (7), rope or other, stretched which constitutes the leading edge of the car- lure.

5. Sailing machine according to the preceding claim 4 characterized in that the sail comprises a triangular piece (14) of fabric, canvas or the like, ten- of the (open sail) between, on the one hand, the flexible link (7) which constitutes the leading edge of the sail and, on the other hand, the 2 parts of canvas (5 and 6) which constitute the 2 main planes of the sail, this piece of canvas (14) po- before covering the 3 small bars (8, 9 and 10).

6. Sailing craft according to any one of the preceding claims. characterized in that the base of the mast (15) has a small seat (16) on which one sits on, the machine, used in hang gliding, being then guided by the orient- tation given to the bar (1) in relation to the mast (15).
